Effects of electric pulse treatment on shape memory effect and microstructure in a pre-deformation Fe13Mn6Si13Cr4Ni0.1C alloy were investigated. The results indicate that electric pulse treatment can accelerate migration of Cr and C atoms and precipitation of Cr23C6 carbides, lower ageing temperature, shorten ageing time and induce nucleation of Cr23C6 carbides. Therefore, the shape recovery ratio was improved to 87.2% from 32% of a water-quenching alloy within 300 s in a Fe13Mn6Si13Cr4Ni0.1C alloy by 300 V, 1100 μf, 1 Hz electric pulse treatment after 10% tensile pre-deformation compared to alloys aged at 973 K, 1073 K respectively following the same pre-deformation.
